Colocation hosting Discussion of the basics
You need a Barracuda firewall to kill those viruses before they cause any damage and to block that spam from ever reaching your network in the first place. The Barracuda firewall is a best in class anti spam security system specifically designed to protect email servers from phishing, spyware, viruses and spam. It employs twelve distinct layers of defense, including network denial of service protection, rate control, IP reputation analysis, sender authentication, recipient verification, virus scanning, policy, spam fingerprint check, intent analysis, image analysis, Bayesian analysis, and rule based scoring. Barracuda firewalls have no trouble fitting into networks both large and small and work well with all types of email servers. One Barracuda firewall can easily handle as many as 100,000 users, and several firewalls can be combined to serve an even larger user group.
